Wind power as a source of harnessible energy is assessed. Average data over the 10 year period, 1985-1994, have been compiled for 12 different widely spaced locations in Oman. It is concluded that the three most promising sites for the economic harnessing of wind-power are Thumrait (latitude 17.67 degrees N and altitude 466.86 m above sea level), Masirah (latitude 20.67 degrees N and altitude 18.80 m above sea level) and Sur (latitude 22.54 degrees N, and altitude 13.7 m above sea level). These locations are situated in the Southwest monsoon region of influence. The largest wind speeds occur during the summer from June to August. The highest (i.e. similar to 10 m s(-1)) long-term (i.e. over 10 years) monthly mean wind speed is that for Thumrait and ensues during the month of July.
